Background In September 2013 the Intergovernmental Panel on Climate Change (IPCC) published its 5th Assessment report, the first comprehensive assessment of physical climate science in six years, constituting a critical event in the societal debate about climate change. This research investigates the content of that debate on Twitter.
Research Questions: 1) What kind of topics and meanings integrate the (structural) communities? 2) What kind of topics and meanings differentiate the (structural) communities?
Data Tweets containing the acronym “IPCC” were collected between September 17 and October 8, 2013 (with http://lexiurl.wlv.ac.uk/) Users stance (convinced, neutral, sceptic) in climate change debate coded by Pearce et al. (under review) The content of these users’ tweets as data
Climate change on Twitter: topics, communities and conversations about the IPCC Pearce, Holmberg, Hellsten & Nerlich (under review). 239 usernames coded according to their stance in the climate change debate as convinced, neutral, sceptics
Methods Semantic networks of each group: 110 most frequently used noun phrases in the tweets (extracted with VOSviewer) Projected the maps for each group on to a base map, which showed the comprehensive situation (visualization with Gephi)
Example tweets This is fraud. This is IPCC fraud. Why have the AR4 projections mysteriously disappeared or been changed? http://t.co/5liqycDmt7 #IPCC in #AR5: "Most aspects of #climate change will persist for many centuries even if emissions of #CO2 stopped" Climate Models Used By IPCC Fail To Reproduce Decadal & Multidecadal Patterns Since 1850 @*…+ http://t.co/n4drUNCF1d @IPCC_CH: Information about the #IPCC and how it produces reports http://t.co/pT6N5t4xQ1 #AR5 #climatechange #Globalwarming is real and human beings are responsible: #IPCC http://t.co/lhnsXZBtXg #nature #world #environment #mot…
